That's all I needed thanks. I just wasn't sure what the correct procedure was in this instance. As I said earlier on, I'm working on RT, and as I venture to further aerodromes, I'm sure that the correct RT procedures will be explained etc. My asking if I should have been given permission/clearance was my own phraseology, not something that I was expecting from the A/G Service. It was more 'Should he have advised me there was one in front?' I know that the decision making process is down to the PIC and not the service.
Thanks
